Ok, so I want an anemone for my clowns, but I cannot have it travelling around my tank as I have a gyre wavemaker and potentially adding another powerhead (and will be adding corals soon). Has anyone ever bought or made plastic buffers to block of portions of their tank? The idea would be to let the clowns leave through cracks if they want, but keep the anemone in a controlled area. IF that wouldn't work does anyone have other ideas? I am looking to get a chicago sunburst eventually.
